Tol all 'whom'z't ma'y concern:

Beitkno'wn Ythat I, ALBERT Bo'wnns,` citi'- z'en of-lthe United States, residing in` the city of,i South'Bend, countyrof St. Joseph, and' State fof Indiana; have invented fai new and useful Detachable Bicy'cle-fHandle-Bar Grip; of which' the fotlowi-ng l'is especification. Myinvention-relates@ impmvemeats-in detachable bicycle" ha'ndle-bar'v` gripa i vehicu-l thronglrL a wedge' action influenced by the operation? of a'2screvv-'threadedbol'o sihaak"the'-iiepenative'partel vofthe fhandlebar'fa'ndhandl'e'properffare frictia'lly" held in operative position. I

'Ihezob'pe'ets ofmyf' improvement are, first, to provi e a grip with a durable and4 eiiicient clamp, said clam beinge'nstucted throughout of metzil'f 0nd,?'gt'6 `provide a clamp having positive -iI'iear'is'l ofA guiding itself into the tubular handle-bar as described libifti* Third',L t`'''poiid a grip with a clamp fitted with a nut so p'laiced11 upon the screw or bolt as to prevent the said clamp from expanding when the grip is being drawn off the handle-bar, thus allo-W- ing the clamp to be drawn freely out of the handle-bar as hereinafter described.

In the accompanying drawing Figure l is a longitudinal section of my improved grip.

Fig. 2 is a perspective view of the .expand-l ing spring.

Fig. 3 is a perspective view of the wedge nut.

Fig. 4 is a view of the threaded bolt showing a nut screwed to the end of the thread for the purpose hereinafter set forth.

The different parts are designated by numerals: 1, is a grip preferably of wood which fits over the handle-bar 4; 2, is a covering preferably of rubber fitting ti htly over the grip 1, and is held in place y a metal ferrule, 3, which clenches into a groove around the grip, 1.

The grip, 1, is bored out centrally through portion of its length, to admit the handle- From the end of this bore to the end of the grip, 1, is bored also centrally a smaller passage for the insertion of the threaded bolt, 6, a metal washer, 7, being interposed between the end of the grip, 1, and the head of the bolt, 6, to prevent the head of the bolt, 6, from cutting into the 0Tip, 1.

5, is the expanding spring of fiat metal.

The spring, 5, is bent to form two extend ing farms. These arms are' beni; b'ac'kwardly andfforward ltofthreeftimes their thickness fori a'portion of: their length formingfthe shoulders markedgsll; in Fig; 2l

The ends of the spring arms are'bentinwardLa'sshown in.E Figs. .1 and 2, `for the purpose-'of guiding-the sprin g.' 5 into '.the.: tubala'r 'hand-ie bar, 4,1.when the grip.v isubieinfg iat; tachedftothefhandlerbar;

L, l., .1' IIwonpposite taperihgrsides of .the wedge nut, 9. which bear upon the sho-ulders 11, are Het 'ander fthe sxneewdtliesthisprng -artn's'i thus forming a wide bearing, preventing the turning of the Wedge nut, 9, independently of the spring, 5.

The Wedge nut, 9, is bored out. centrally and threaded to admit the bolt, 6.

8 is a threaded nut screwed to the end of the thread on the bolt, 6, and securely tightened. The nut, 8, must be of a size that will turn with the bolt, 6, between the spring arms, 5, without striking said spring arms. When the grip, 1, is beingfdrawn off the handle-bar 4, the spring 5 is drawn out of the tubular handle-bar, et, by the nut, 8.

As will be readilv seen Without the nut, 8, the spring, 5, would be drawn out of the handle-bar, 4, by the Wedge nut. 9. The wedge action of the nut, 9, would slightly expand the spring, 5` thus preventing the spring. 5, from drawing freely out of the handle-bar 4:. The elimination of this diiculty being an ilnportant feature of my improvement.

In assembling the parts the spring, 5, is inserted into the grip, 1. The bolt, G, is then inserted through the small passage in the end of the rrtrip. 1, and through the spring, 5, a washer, 7, being interposed between the head of the bolt. 6, and the grip, 1. The nut, 8, is then screwed to the end of the thread on the bolt, G, and securely tightened.

The wedge nut, 9, is then placed between the shoulders, 1l. The bolt, 6, is then given a few turns by means of a screw-driver to start it into the Wedge nut, 9. Thus the i projectionslO of the spring 5, into the grip,

l, thus locking the spring, 5, and grip 1 securel together.

W en the bolt, 6, is turned drawing in thewedge nut, 9, the wedge action expands the spring arms, 5, against the interlor'of the tubular handle-bar, 4:, thus frictionally holdingthe-fgrip and the handle-bar firmly together.

I am aware that gripsk provided' with "5 clam s fitting inside of ,the-tubular handlebar,y ave been madeprevious to. my invention, therefore Indo not-claim'thls combina# tion broadlyY but"`I-c1aim f 1. `A .detachable `bicycle handle-barl grip provided with a metal expanding clamp consisting tof, "sa spring having-'two extending @epics otfthlllpatent inly beotitained for arms, their ends being bent inward for the purpose of guiding them into the tubular handle-bar, two opposite shoulders formed by bending the spring arms backward and forward to three times their thickness for a portion of their length, a tapering wedfve nut fitting between said shoulders, a threa edbolt passing through the end of the grip and through the base of the expanding spring and into a threaded opening in the wedge nut', whereby, when the screw is turned drawing the wedge nut in and expanding the spring arms against the interior of the tubular handle-bar, the grip is frictionally held in operative -positicn.

v2. A detachable handle-bar `grip as specified in claim 1 in which the threaded boit passing through they end of the grip and through the base ofthe expanding spring is provdedwth a nut which clampsjthe expandingspring to the end of the orio.
